i wonder if you can talk about biden's role in the administration. what it says that he was tapped for the role about his status in administration. this was a moment when we say wow, this has been one of the more consequential vice presidents? >> biden has been influential in a way that was not appreciated. chuck hagel seems to be on his way to being secretary of defense. they are very close and i don't know that obama had a deep relationship with him, but there other ways in which his fingerprints are on the president's policies and afghanistan won the argument. two things here i would add on guns specifically. biden in a way is -- a messenger for obama and sectors that may not trust him. he's got working class roots from industrial pennsylvania. he's catholic. i guess that the white house sees him as a messenger to people who might be skeptical and have ideas of what obama's agenda is and that biden could be a better messenger on this. i hate to bring up the 2016 number, but i think you may see more opportunities for biden to step out and prove him
